SPECIFICATION forming part of Letters Patent No. 627,260, dated June 20, 1899. Application filed March 3,1898. Serial No. 672,371. (No model.)

To LZZ whom it may concern,.-

Beit known that I, STAOY B. HART, a citizen of the United States of America, residing at Peoria, county of Peoria, and State of Illinois,

have invented certain new and useful Improvements in Two-Vay Pivotal Couplings, of which the following is a description.

Referring to the accompanying drawings, wherein like reference-letters indicate like ro or corresponding parts, Figure l is an elevation of a two-way pivotal coupling embodying my improvements. Fig. 2 is asection in line 2 2 of Fig. 1. Fig. 3 is a section in line 3 3 of Fig. l. Fig. 4E is a similar section showing a modification. Fig. 5 is an end View of a grain-separator, showing my device as applied to the elevator-tube, the dot-lines showin g the elevator with the foot swung outward from the machine to clear the wheels zo and other parts when folding down upon the top of the separator; and Fig. 6 is a side view of a grainseparator, showing in dotted lines the grain-elevator in the act of folding down upon the top-of the machine.

The object of my invention is to provide a simple, effective, and economical two-way hinge, joint, or coupling device for use in any case where it is desired to give a part a y double movement, the two being at an angle 3o to one another. My invention accomplishes this in a satisfactory manner; and it consists in the novel construction and combination of parts shown and described, and particularly pointed out in the claims.

I have shown my invention as applied to the elevator-tube of a grain-separator and will describe its use as thus applied; but I do not wish to limit myself to such use, as it is equally well adapted for use for many 4o other purposes.

In the drawings, A represents the grainseparator, provided with a transverse bar or pipe B, (preferably a gas-pipe of suitable size,) extending partly or entirely across the 45 top of the machine and adapted to support the elevator-tube C.

My improved device is adapted to form the connection between the elevator-tube and the support B. For this purpose I provide a 5o separable sleeve D, composed of the parts d and d and provided with means to temporarily hold the two parts in proper relation to one another. The sleeve is of a suitable size to embrace the bar or pipe support B, and a nut or bolt E, connecting the parts d and d', furnishes the means to firmly clamp the sleeve to the support when desired. The foundation for the sleeve is a plate F, forming one part ofthe sleeve D, to which the movable part of the sleeve may be pivotally connected or hinged, as shown at d2, or otherwise suitably connected.

A second plate G, to which the elevatortube is firmly secured and against the face of which preferably the face of the plate moves, forms the base of the entire device. A bolt H, loosely extending through the plates G and F, permits the necessary movement of the two plates to form the pivotal action desired.

The mode of operation is as follows: The

vator-tube is in its working position, (shown in full lines in Fig. 5,) the sleeve is firmly clamped to the support, andthe lower end of the elevator tube or foot is also temporarily secu red to the machine in any preferred manner. Vhen it is desired to turn the elevatortube down upon the top of the machine for transportation purposes or for the purpose of passing the machine through a low door, or for any other purpose, the elevator-tube is disconnected at its bottom from the machine and the foot swung outward, Fig. 5, to clear the wheels and other obstructions on the machine. The nut or screw E is then loosened by the handle e or other means, and the elevatortube may then be rotated on the sleeve-andsupport connection, Fig. 6. The elevator may then be laid down upon the top of the machine and secured in any suitable manner.

Having thus described my invention, what IOO I claim as new, and desire to secure by Letters l. The combination with a supporting-bar, of a two-way pivotal coupling comprising a member G provided with means for securing it to a part, a member F pivotally connected to said member G, a member d hingedto said member F and constituting with it a sleeve embracing said supporting-bar, and a clamping, means for clamping said members F and d on said supporting-bar, substantially as described.

2. In a two-Way pivotal coupling, the combination of va cylindrical supporting-bar, a member G provided with means for securing the same to a part of a machine and having a vJlat face, amemberV F having-.la'iiat face Workngon said iiat faceoifthe1member G and having a substantially semieircular bearing for said cylindrical supporting-bar, a bolt pivotally securing said members F and G to.- gether, a member d hinged to said member F and having a complementary bearing for said supporting-bar, said members cl and F constituting a two-part sleeve embracing said Asupporting-bar, and a hand clamping device for clamping said sleeve onto said supportingbar, substantially as described.
